The DNS encodes the <local-part> as a single label, and encodes the
|
|
<mail-domain> as a domain name. The single label from the <local-part>
|
|
is prefaced to the domain name from <mail-domain> to form the domain
|
|
name corresponding to the mailbox. Thus the mailbox HOSTMASTER@SRI-
|
|
NIC.ARPA is mapped into the domain name HOSTMASTER.SRI-NIC.ARPA. If the
|
|
<local-part> contains dots or other special characters, its
|
|
representation in a master file will require the use of backslash
|
|
quoting to ensure that the domain name is properly encoded. For
|
|
example, the mailbox Action.domains@ISI.EDU would be represented as
|
|
Action\.domains.ISI.EDU.
